Happy new all Can any of you chaps point me in the right way for fitting an 850 header on a Sprint? A photo would be great help or directions for pipe work using a standard Sprint rad.
Any help much appreciated
Many thanks,

Tony.

The top connection is 8mm bore hose from the thermostat housing. A one metre length will suffice.
The outlet is 19mm bore and goes to the bottom radiator hose via T-piece. I route the hose around the back of the engine
using a 45 degree elbow on the tank joined to a one metre length of 19mm hose.

I disagree with James's positioning of the the tank because it is not high enough to clear the engine,
being too low, the low level sensor won't be triggered until after the coolant level has dropped within the engine.


This position takes advantage of the space the bonnet's skeleton allows to get as high as possible.
All the coolant in the tank is above the engine.
Furthermore you can simply fill (or top up) the coolant via the header tank. There is no longer a need for the cap in the thermostat housing.

Hi Ian, i was already thinking about that but your bottle looks different to the one James has used? Or is it just the photo?

This was the one i was thinking of.

Thanks,

You will have problems fitting the header tank in Ians location on a sprint as the head is bigger than an 1850.

The bottom hose also gets very close to the exhaust manifold. Fitting it in the location I used on RUK is fine.

There's a brake thingy in my way.

MUCH easier to fit on the RHS of a LHD car as the plumbing for the tee into the bottom hose is much shorter and goes nowhere near the exhaust! As i'm perfectly sure you can work out for yourself Jeroen! I think you're just trying to mess with our heads!

Although I have a Vauxhall engine and a Saab rad, the relative hose positions are almost identical to a Sprint. I elected to use a Volvo 240 header tank, which is shallower, wider and tapered towards the front, mounting it in front of the strut turret on the RHF flitch to minimise pipe lengths. It works fine for me, but my stat is lower than a Sprint one. And, of course, my battery is in the boot.

That is a Sprint, James!

On your second point, that is what the 45 degree is employed for, to keep the hose clear of the exhaust.
